To make an oblique cut, the guide heads are offset laterally with respect to each other so as to impart a constant slope to the axis of the electrode wire, which can reach up to several tens of degrees.

とりつけられた電動機により行なわれうる。Various methods have already been proposed to solve this problem. Some of them, for example, consist in establishing a mechanical or electrical connection between the lateral movement of the guide heads and the orientation of the guides on these heads (US Pat. No. 1,443,1896). The assimilation of the orientation of the two guide heads is achieved by a ventograph-controlled linkage (D
BE-0084083) or by an electric motor mounted on the guide head.

4 represents a lower guide head, and 5 and 6 represent two electric motors used to move the part 1 in the X and y directions, respectively. In order to obtain the desired slope in relation to the perpendicular to the cutting plane (indicated by α in the figure), the upper guide head 3 is supported by a cross table, the tables 7 and 8 of which are oriented relative to the cutting plane. Electric motors 11 and 12 in two parallel different directions U and V
is driven by. These electric motors, like the electric motors 5 and 6, are controlled by the NC control I device 13.

機２１及び２２に伝達される。In order to obtain the data necessary for the orientation of the guide head, the movement of the crosstable in the U and V directions, i.e. the lateral displacement of the guide head in relation to each other, is measured by two position sensors 17 and 18, one of which , the vertical position of the head plate 14 is determined by a position sensor 19. This position sensor 19 makes it possible to ascertain the separation distance between the guide heads, measured with respect to the vertical line. The signals emitted by the position sensors are transmitted to two electric motors 21 and 22 via a correction circuit 20 for correcting data regarding the positions in the U and - directions depending on the vertical separation distance between the guide heads.

機械的結合により実現できるからである。It should also be noted that by choosing methods other than those described above for actuating the clod jack, hydraulic control of the orientation of the guide head can be achieved. Thus, the correction circuit 20, whose purpose is to make the slope of the electrode line independent of the vertical separation of the heads,
2 can be directly controlled by the signal controlling 2. Note that it is not necessary to control the clod jacking via electrical signals that reflect the movement of the cross table. This control can be realized, for example, by a variable rate mechanical coupling between the movement of the cross table in the U and V directions and the movement of the corresponding piston of the mountain jack.

は容易に理解できる。Numbers 31 and 32 represent the upper and lower parts of the case in which the so-called guide head 33 is mounted. This case is provided with a guide 36 having a hole near one end and used for centering the electrode wire (not shown in FIGS. 2 to 4) passing through the tube, and a guide 36 near the other end. The part is a tube 34 which is doubled with a sheath tube 35.
is attached. This tube is held in a lower ball joint 37 in a state centered on the guide hole, and slides in an upper ball joint 38 that surrounds the tube at approximately the center. The lower ball joint 37 is mounted in a lower cage 41 that is integral with the lower part 32 of the case. Upper ball joint 3
8 is driven by the upper plate 44 so that it can slide in the V direction under the action of the receiving jack 46 (
2), and is mounted in the upper cage 42 in a manner driven by a lower plate so as to be slidable in the U direction under the action of a receiving jack 45. Each plate 43 and 44 has one slit 49 and 5o,
This is perpendicular to the direction of movement of these plates so that their movement is independent. The pistons of the receiving jacks 45 and 46 are returned by springs 47 and 48, respectively. With this arrangement, the receiving jack 4
It is easy to see that the action of the fluid under pressure acting on 5 and 46 allows precise orientation of the dowel 33 into the guide.
